Gempen, or Schartenfluh as it is more formally known, is a popular crag in a beautiful location, with great views over the surrounding countryside. It is possible to see the Alps on a clear day, and the sunset is well worth waiting for. There are 4 main sectors, all with their own character. The rock is mostly solid, and getting polished on the popular routes. It dries very quickly, and Sandührliwand in particular catches all the sun that is going, so can be busy on a nice Sunday afternoon in autumn, winter and spring.
